True or False: A mature tree with good species tolerance requires 0.75 feet of protection per inch of DBH.

The statement that a mature tree with good species tolerance requires 0.75 feet of protection per inch of DBH (Diameter at Breast Height) is accurate. In arboriculture, particularly when considering the protection needed for trees in urban and utility environments, a common guideline is to allocate a certain amount of foot protection per inch of DBH to ensure the tree’s health and stability.

Specifically, 0.75 feet of protection means that for every inch of the tree's diameter, there should be a corresponding 0.75 feet of space around the tree’s root zone to accommodate its growth, minimize compaction, and reduce competition for resources like water and nutrients. This protective zone is essential for maintaining a tree’s vitality, especially in areas where human activity or utility operations might otherwise encroach upon the tree’s root system.

The other choices suggest different interpretations or amounts of protective space, but the established standard for good species tolerance is indeed 0.75 feet per inch of DBH, highlighting the importance of adhering to the accepted guidelines in tree care practices.
